Rockhounding in WA: How to start hunting minerals, fossils and gemstones

Washington is full of dazzling minerals and fossils - you just have to know where to look.

But getting started as a so-called rockhound, or a collector of minerals and fossils, can be intimidating.

A complicated web of local, state and federal jurisdictions cover Washington's land. Many rockhounds are tight-lipped about their hunting spots. You can spend hours going over a spot and find nothing, or discover you've brought the wrong tools for the job.

Many longtime rockhounds say the best way to get started is to join a field trip hosted by a local rock club or the Washington State Mineral Council. You can take advantage of members' expertise on where to look and learn more about how to best prepare for a successful trip.

"It's just a great group of people to socialize with when you go on field trips," said Susan Gardner, president of the North Seattle Lapidary and Mineral Club.

If you're just interested in looking at pretty rocks, a number of local clubs also host public rock and gem shows throughout the year.

But if you're hungry to sniff out some treasures, here's how to get started on your rockhounding journey in Washington, according to local experts.

What kinds of minerals and fossils are in Washington, and where can I find them?

Orange-y red carnelians are plentiful in Southwest Washington, and sometimes wash up on the state's shores and creekbeds. (A cherished spot for carnelian hunting, Damon Point in Grays Harbor County, is now closed over safety concerns related to high tides and erosion.)

In Central Washington, there are prized "Ellensburg Blue" agates and bountiful petrified woods, ancient waterlogged trees that crystallized after being entombed in lava flows roughly 15 million years ago. The preserved remains of more than 50 species of trees can be seen at Ginkgo Petrified Forest State Park.

In Eastern Washington, people can collect noble serpentine for a fee during public dig days at Wild Turkey Mine, or search for plant and insect fossils at the Stonerose Interpretive Center & Eocene Fossil Site in Republic, Ferry County.

Closer to Seattle, a popular spot for collecting quartz crystals is Hansen Creek in Mt. Baker-Snoqualmie National Forest. But collecting there can be a daunting trip even for seasoned rockhounds, said Nique Wicks with the Washington State Mineral Council.

Where can and can't I collect?

To collect on private lands, you must have permission from the property's owner. Public lands managed by the U.S. Forest Service or the Bureau of Land Management generally allow people to collect a "reasonable quantity" of minerals and common invertebrate fossils (like clams or snails) for noncommercial use.

Some parcels of public land may be under a mining claim, meaning someone has secured the right to extract mineral deposits from the area. Always check an area's collection rules and ownership before heading out.

Collecting rocks, fossils or any natural item at Washington state parks, national parks, national monuments, national wildlife refuges, national scenic areas and on tribal lands is never allowed.

When are permits required?

Meteorites, vertebrate fossils and any archaeological or historic artifacts cannot be collected without a permit, which are only granted for scientific purposes. If you find any of these items, contact the state or federal agency that oversees the land.

A special rule about petrified wood: You can't collect more than 25 pounds plus one piece per day, up to a maximum of 250 pounds per year. You also can't trade, barter or sell the petrified wood without a contract from BLM.

How do I find out exactly where to search?

Collectors may share location coordinates or driving details online, in Facebook groups or on rockhound forums, public databases, personal blogs and YouTube channels. Hang around the community long enough, and some friendly rockhounds may be willing to share details or advice.

Jean Shaffer, with the North Seattle Lapidary and Mineral Club, recommends people check out two books: "Rockhounding Washington: A Guide to the State's Best Sites" by Lars W. Johnson, and "Gem Trails of Washington" by Garret Romaine.

"They have different sites, so you can go and look through the book and find out if they're open to the public, and then make a little field trip of it," Shaffer said.

But she, like many other rockhounds, recommends people join a rock club field trip first before striking out on their own. Rock clubs can help beginners learn tips and tricks, and they often have access to otherwise private areas.

What tools should I bring, and what other kinds of preparation should I do before heading out?

Wear appropriate clothing for the site you're going to, and consider bringing a hat and work gloves. Always have a map of where you're headed that's accessible even without cell service.

As far as gear goes, you don't need much to get started, said Kim Villines, vice president of the East King County Rock Club, but "it definitely helps to have the right tools.

Depending on the kind of mineral you're collecting, you might need a flat chisel, hammer or pry bar. Villines likes using a solid steel rock pick because the sound it makes when striking rock helps her identify the mineral.

Sometimes you can get away with just a hand trowel and a bucket or backpack to haul your findings home. And if you're not near a body of water like a river or lake, a bottle of water can help quickly wash off dirt on the rocks you collect to make sure it's worth bringing home.

Always check weather forecasts, especially for snow, rain or hazards like wildfires or flooding. Tide predictions can also be helpful to check, since it may be easier to collect on beaches during low tide. Some rockhounds suggest hunting after a rain shower, when certain minerals may stand out more in dirt or gravel.

What are some other general commonsense rules or advice?

Rock clubs across the U.S. promote the importance of following the "Rockhound Code of Ethics," which mirrors many of the principles of Leave No Trace. Don't leave trash, build fires only when it's safe, and fill in any excavation holes or tunnels that might harm animals. Basically, leave a site better than you found it.

Don't get discouraged if you're having trouble finding interesting stuff. Part of the fun is the "treasure hunt" aspect of rockhounding, said DuPont rockhound Shell Hallahan, who often searches for agates with her daughter along Puget Sound's beaches. "You never know what you're going to find out here," she said.

Even if you don't find a gem, rockhounding allows you to get out in nature and exercise, she said. "So it's never a bad day, even when I don't find an agate, she said.
